Battle of Guttstadt-Deppen

The Battle of Guttstadt-Deppen (5-6 June 1807) was a battle of the War of the Fourth Coalition that was fought between the French Empire and an Allied army of Russian and Prussian troops. The battle was fought in Guttstadt, East Prussia (now Dobre Miasto, Poland).

At the beginning of June 1807, Count Levin August von Bennigsen launched an offensive against the forces of Emperor Napoleon I in East Prussia. Bennigsen planned to trap Marshal Michel Ney's corps between several converging columns. To occupy the French troops on Ney's left, Bennigsen sent Anton Wilhelm von L'Estocq's Prussians to assault Marshal Jean-Baptiste Bernadotte's troops at Spanden and ordered Dmitry Dokhturov's Russians to assault Marshal Nicolas Soult's men at Lomitten. All three French marshals saw sharp fighting, but the Russian plan failed to put significant numbers of French troops out of action. Afraid of being cut off in turn, Bennigsen ordered a retreat, and the two armies met again a week later at the Battle of Friedland.
